This BT136 Triac-based 230-volt AC motor speed control circuit is designed for adjusting the speed of an electrical motor in your home like a drilling motor or dress stitching machine motor.
The speed of the electric motor was adjusted by using the Preset pot on the circuit diagram.

so in this article, I’m going to explain in detail how to control the electric motor speed control using Triac based circuit. The specialty of this circuit is very few numbers of components are used to control the power AC motors.

- G – Gate of the Triac
BT136 Motor Control Circuit
The motor speed control circuit works based on the Triac of BT136. Adjusting the 500k pot will increase or decrease the running speed of the electric motor.
The Inductor used in the circuit is optional you can use or avoid it ( you can also take the direct neutral without the inductor ).
